[Update]: Just got word from Verizon that the problem has been identified and that a fix is on the way. Take a look at the full quote below for more information.
If you are one of the 500,000 subscribers using Verizon’s 4G LTE network, don’t be alarmed if you are no longer receiving an LTE signal where you once did. Verizon’s 4G services have been experiencing outages over night and this morning, meaning owners of the HTC Thunderbolt might have to settle with 3G for now. If you can’t even receive a 3G signal, well, that’s the phone’s poor 3G/4G switching rearing its ugly head.
We expect Verizon will have the issue cleared up shortly. They’d hate to have the shiny new LTE network still experiencing problems tomorrow when they launch their second LTE handset and first of the Droid line to deploy 4G.
We are aware of an issue with 4G LTE data connections and our network engineers are working to resolve this quickly. We have determined the cause of our issue and are working with our major vendors to restore connections.
* 4G LTE Smartphones will still be able to make calls.
* Customers are temporarily unable to activate any 4G LTE devices.
* Please note: Customers may experience a 1XRTT data connection during this time.
* After determining the cause of our 4G LTE network connection issue, we are continuing to work to restore connections.
* We expect to see the network restore on a market-by-market basis. Timing and additional details will be provided as they become available.
